Hello, everyone, I have been struggling quite seriously with the titular problem, having lost whole scores... By chance, I found the culprit - in my own doing... While keeping the Finale file open .. I would use a computer-cleaning app .... DO NOT DO THAT!                                            At the moment I stopped doing  that, my problem fully disappeared. Don't know whether Finale people could do something about it. Would have been nice.
